Hi, I was hoping someone could help me re-install iTunes. I'm not sure why I'm running into this problem. When I try to run it now, I get an error that says, "This action is only valid for products that are currently installed." When i try to reinstall iTunes with a download from the iTunes website, I also get an error saying old product cannot be removed. iTunes is not listed in the "add/remove programs" Anyone have any ideas? Thanks in advance.
